Paper Abstract

During the deterministic processing, dwell time map is the precondition to achieve the high precision surface. It is very important to obtain V-like shape removal function for the dwell time computation when using the numerical iteration method. As one of the ultra-precision polishing method, Fluid jet polishing (FJP) has been used widely in optical fabrication. But the shape of removal function of existing vertical jet polishing is W like. So, eccentric rotation jet device was usually used to correct the shape of remove function from W-like to V-like shape. In this paper, we put forward a concept of rotary function, and its can take the place of eccentric rotary device to achieve faster solve of dwell time and make the equipment structure simplify. We also put forward the layer by layer dwell time computation method and efficiently avoid the convergence failure.
